Playing devil's advocate:

Maarb. A Titan is a massively expensive machine of war. It takes months to build and billions upon billions to afford. Only massive corporations or alliances can afford to make or field them, and that's after a **** ton of infrastructure and groundwork by whole groups of people. They are fielded in massive scale conflicts sometimes involving hundreds or thousands of players. The pilot literally cannot leave the ship once he is plugged in, and piloting one is something you're given permission to do from whatever organization made it. They can't dock in a station. They have to be guarded around the clock at a corporation run starbase. They have to have scout ships light waypoints for them to even be able to move between systems. They literally can't go anywhere by themselves. And when they do go anywhere, spies call out to hundreds of players that it's on the move, and whether it's vulnerable to a massive assault. People will bring ships from light years away to try and kill a Titan.

You will not be mission running in one. And by the time you're able to pilot one... you'll know how to fit it.
